Check Digit Verification of cas no
The CAS Registry Mumber 66019-20-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,6,0,1 and 9 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 66019-20:
(7*6)+(6*6)+(5*0)+(4*1)+(3*9)+(2*2)+(1*0)=113
113 % 10 = 3
So 66019-20-3 is a valid CAS Registry Number.
